有效性

After flow and transient stability calculating of the 330kV grid, we got the over-load and hazard lines set. Then we gained the redundant network needed to be built according to the increasing power supply and load in 2010. Adopting regradation step-by-step algorithm by which we can improve the calculation efficiency , we compared the validity of every line, deleted lines with low validity until no redundant line is in the network. At last we got the target network framework adopting the improved ant colony algorithm. Flow distribution, construction investment assessment and target framework of Gansu long-term planning all be considered, from the viewpoint of to be economic and reliability the feasibility of the improved ant colony algorithm is discussed.

在对2006年该网架结构进行了潮流计算与暂态稳定计算分析后，得出了系统的过负荷与危险线路集，并针对2010年新增的电源和负荷点确定了冗余的待建网架，然后利用逐步倒推法比较各待选线路在系统中的有效性，逐步去除有效性低的线路，直到网络中没有冗余线路为止，以此来以提高优化算法的计算效率，最后利用改进后的蚁群算法确定优化后的目标网架结构，并从潮流分布、建设投资估算等方面与甘肃电网远期规划中确定的目标网架进行了比较，从可靠性和经济性角度论证了改进蚁群算法在网架优化中的可行性。

There are no grade I document and lack of the study of validity in long term and essentiality and validity of retreatment.

If any provision of this Act or application of it to any person or circumstances is held invalid, the invalidity does not affect other provisions or applications of the Act that can be given effect without the invalid provision or application, and to this end the provisions of this Act are severable.

如果本法的任何部分或者其对某人或者在某种情况下的适用被判定为无效，该无效性不应影响本法其他部分的有效性或者除该无效部分或者无效适用之外的本法适用的有效性，在该意义上本法的各个部分是可分的。

If any provision of this Act or the application thereof to any person is held invalid, the invalidity shall not affect other provisions or applications of the Act which can be given effect without the invalid provision or application and to this end the provisions of this Act are severable.

如果本法的任何部分或者其对某人的适用被判定为无效，该无效性不应影响本法其他部分的有效性或者除该无效部分或者无效适用之外的本法适用的有效性，在该意义上本法的各个部分是可分的。

The analysis of effectiveness on policy making and implementation of Slopping Land Conversion Program is important as the evaluation of effectiveness is always a vital part in program appraises.

费用有效性评价是工程评价的重要方面，从政策制定和执行角度对退耕还林的费用有效性及其影响因素进行分析，具有重要的意义。

This paper takes HuBei province for example and use principle of industrial structure market validity to finish a test and verification on the unrelative relation between degree of industrial structure market validity and similar degree of industrial structure.

本文以湖北省为例，运用产业结构市场有效性原理验证了产业结构市场有效性程度和产业结构相似程度无关的命题。

Methods Based on the internationally accepted de finition of QOL and the clinical characteristics of uterocervical cancer as wel l as the existing QOL scales, we designed the QOL-UCC.

对 113例宫颈癌患者用QOL UCC评估生存质量，以考察量表可信性、有效性及可行性。其中被测者信度、重测信度、分半信度、克朗巴赫系数表示量表可信性，准确关联效度、结构效度、反应度研究表示量表有效性，量表完成率及完成时间表示量表可行性。

This distortion measure can reflect the different validness of each dimension with different distribution in feature space,so that it can not only improve the speaker recognition system performance but also enhance the system time robustness.

由于不同分布的各维参数对话者识别的有效性各不相同，因此，文章提出了一种能反映这种有效性差别的失真测度，即：方差归一化失真测度。

Mark J1C at theintersection of the two lines.It is necessary to use a new standard specimen to do J-integral test. The dimension of standard specimen is 10 mnx20 nsnxiOO mm .The results from this specimen are satisfied with the condition of validness of J-integral as well as the condition of plane-strain. The reason is explained.

通过对J积分测试中的有效性条件及平面应变条件的分析，提出用尺寸为10mm×20mm×100mm的试样作为标准试样进行J积分试验，该试样既能满足有效性条件又能满足平面应变条件，并解释了其原因。

The effectiveness and reliability of science are necessary for authenticating the objectivity of evidence, and it is urgent to filter scientific knowledge to guarantee effectiveness and reliability of science.

科学的有效性和可靠性是鉴定证据客观性的必要条件，而科学的有效性和可靠性需要对科学知识加以过滤。
